不同栽培技术措施对油用牡丹生长量的影响研究

Effects of Different Cultivation Techniques on Growth of Oilssed Peony Paeonia ostii

在鲁西南种植区,以“凤丹”油用牡丹3年生苗为试验材料,测定了不同处理下油用牡丹种植1年后其植株高度、地径大小以及复叶小叶数,探讨不同整地规格、栽植深度、栽植密度对油用牡丹生长量的影响,以期为油用牡丹高效栽培技术提供理论依据。研究结果表明,“凤丹”牡丹在鲁西南地区土壤翻耕深度为20~30cm、初期栽植密度30cm×60cm、栽培深度20~30cm时,株高、地径和复叶小叶数等生长量最大。

In peony planting area of southwest of Shandong province,the 3-years old seedling oilseed peony‘Fengdan’were treated with different deep tillage,planting densities and planting depth,and the growth including of plant height,basal diameter and compound leaflets were calculated and analyzed in order to screen out the optimal cultivation techniques.The results showed that‘Fengdan’was treated with deep tillage 20 cm-30 cm,planting densities 30 cm×60 cm,planting depth 20 cm-30 cm,the growth of‘Fengdan’was significantly higher than that of the other treatments(P<0.05),and the results were optimal deep tillage,density and planting depth of high yield and efficient cultivation in southwest of Shandong province.
